"Over two years ago a group was founded to reverse engineer the Broadcom Wireless LAN chipsets to provide Linux drivers. This chipset is used by many OEMs, for example in Apple’s AirPort Extreme in Power- and iBooks, Linksys’ WAP and WRT series of consumer grade wireless routers, various laptops from Acer, Dell, Gateway, HP and others and many more external and internal devices, including CardBus cards. That work has now come (.pdf) to a first milestone as there now is a free (GPL2 or later) Linux driver for a variety of these chipsets."
